We know people die but we never think of anyone who is close to us that they can die too. The person who dies is not in pain but the people who are left behind feel the pain. That pain is unbearable when you take slow steps towards the graveyard knowing that you will return leaving that person behind and will never see him again, that feeling of helplessness will make you weak. In the graveyard, when you see the body of that person, each and every memory with him flashes in front of you and you feel only one thing which is 'AGONY'.
Now comes the hardest part, the journey back from the graveyard. You feel that something is missing, the feeling is so intense that you cry, shout and fell down from your feet but nothing happens, The truth remains the same.
That journey is the saddest and the longest.
You know when the journey ends?
The time when someone else takes on this journey from you by leaving you behind.
So by this it means that the journey back from the graveyard never ends as you left a part of yourself behind and you will return there someday handling that journey and sadness you carried and the cycle goes on.
